Why does the design example simulation in NCSim or Xcelium fail for the Low Latency 100G Ethernet Intel® Stratix® 10 FPGA IP core variant when selecting the “Enable RS-FEC” or “Enable Dynamic RS-FEC” options?

Description

Due to a problem in the Intel® Quartus® Prime Pro Edition Software version 18.1 and earlier, the design example's simulation for the Low Latency 100G Ethernet Intel® Stratix® 10 FPGA IP core variant with the “Enable RS-FEC” or
“Enable Dynamic RS-FEC” options selected will fail in NCSim or Xcelium. This failure will typically take the form:

*F,NOSNAP: Snapshot 'basic_avl_tb_top' does not exist in the libraries.

Resolution

To work around this issue, do not select either the Enable RS-FEC or Enable Dynamic RS-FEC options in the IP’s parameter editor when generating the design example for simulation in NCSim or Xcelium.
